Laws ultimately restrict anyone standing around (8)
I believe the answer is:
statutes
'laws' is the definition.
(I've seen this before)
'ultimately restrict anyone standing around' is the wordplay.
'ultimately' indicates one should take the final letters.
'standing' becomes 'status' (I've seen this before**).
'around' means one lot of letters goes inside another.
The final letters of 'restrict anyone' are 'te'.
'te' put inside 'status' is 'STATUTES'.
(Other definitions for statutes that I've seen before include "Attest us under written laws" , "Official and written laws" , "Written laws passed by Parliament" , "orders" , "Legislative acts" .)
